FRANK I1. ROSENTRETER, OF ROCHESTER, NEW YORK.

SASH-CORD FASTENER.

SPECIFICATION forming part of Letters Patent No. 559,953, dated May 12,1896.

Application filed November 2, 1892. Serial No. 450,793. (No model.)

To all whom it may concern:

Be it known that I, FRANK L. RosnN- TRETER, of Rochester, in the countyof Monroe and State of New York, have invented a certain new and usefulImprovement in Sash- Cord Fasteners; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the drawings accompanying this application.

My improvement relates to gravity sashbalances, or those in which thesash is balanced by a weight running in a. boxing of the window-case.

It also relates to that class in which a metal band or ribbon is used inplace of the cord ordinarily employed.

The invention consists in the special construction of the fastening forsecuring the band to the sash, as hereinafter described and claimed.

In the drawings, Figure 1 is a sectional elevation of a portion of awindow casing and sash with my improvement attached. Fig. 2 is aperspective view of the attachment for the sash. Fig. 3 is alongitudinal vertical section of the same.

A indicates the window-casing, and B the sash.

O is the flat metallic band or ribbon, D the fastening that attaches tothe sash, and E is the weight and G the pulley over which the bandpasses. The sash-fastening D is of special form, and is designed to fitendwise in a round hole bored in the edge of the sash by a common bit oranger. Therefore it is of approximately cylindrical sha-pe, as shown inFig. 2. The upper rear portion, however, is cut out in a series ofsteps, and it is provided with two cross-bars a b, one in the rear ofthe other,with a space between and located at different levels, thefront one being the higher. The interior of the block below thecross-bars is hollow and in front it has two projecting lips c c,forming offsets, with a space between them sufficient to receive thewidth of the band. At the opposite end and on the under side is adownwardly-projecting lug f. To

attach the band, the end is inserted under the front cross-bar. It isbrought up and around the rear cross-bar b, is then passed under thefront cross-bar a, and then, together with the main length of the band,is turned up at right angles to the block, and rests within the spacebetween the two projecting lips c c. This makes a loop around the rearcross-bar and leaves the two thicknesses of the band in contact aroundthe front cross-bar. The strain on the main length of the band makes thecontact closer, and as there are no sharp bends there is no undue dangerof breakage. The band by being inclosed between the lips c c is shieldedand held from contact with the easing as the band runs up and down andthe parts are held perfectly centered.

The device above described being of cylindrical form is adapted to befitted in a round hole bored in the edge of the sash, while the steps inthe rear give space for the attachment of the band, and the cross-barsserve as a secure attachment for the band.

The strain of the band on the outer end of the device causes the innerend to be tilted downward and the lug f to clamp into the wood, therebyholding the device firmly in place.

Having described my invention, I do not claim simply and broadly a clipprovided with cross-bars to which the band is attached.

\Vha-t I claim as new, and desire to secure by Letters Patent, is-

The fastening D, consisting of a cylinder adapted to fit into a roundhole bored in the wood, constructed with steps on its upper surface,cross-bars a Z) on said steps, lips c c at the outer end, and thedownwardly-projecting lug f at the inner end, as shown and described andfor the purpose specified.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.

FRANK L. ROSENTRETER.
